state & get_primary_mask(another) tested (state & (primary | other)),
which will be true if state matches *either* primary *or* other, but
what is wanted in a not-negated test is state matching all bits of
(primary | other). match_primary_mask does that.
On the other hand there are also cases of "not state & (primary | other)".
no_match_primary_mask handles that, returning true if state matches none
of the bits in (primary | other).
Fixes#10646.
